RE: Chain saw on a stick
Would be nice for that. I have an extendable/collapsing Corona tool I use for that purpose.
What is really nice if you live in the south or anywhere with super thick cutovers is a gas powered hedge trimmer. Makes cutting through all the thorns and regrowth a snap. Easy paths to walk, easy shooting lanes, and the deer will walk them too! The machete or bush axe has its place, but man is a hedge trimmer the way to go!
